MOSCOW (Reuters) - The Kremlin said on Monday that the latest round of U.S. sanctions on the Russian energy sector risked destabilising global markets, and Moscow would do everything possible to minimise their impact.

"It is clear that the United States will continue to try to undermine the positions of our companies in non-competitive ways, but we expect that we will be able to counteract this," Kremlin spokesman Dmitry Peskov said.

"At the same time, of course, such decisions cannot but lead to a certain destabilisation of international energy markets, oil markets. We will very carefully monitor the consequences and configure the work of our companies in order to minimise the consequences of these ... illegal decisions."

The U.S. Treasury imposed wider sanctions on Russian oil on Friday, targeting producers Gazprom Neft and Surgutneftegaz, as well as 183 vessels that have shipped Russian oil.

The move was meant to cut Russia's revenues for financing the war with Ukraine. A U.S. official said the sanctions could cost Russia billions of dollars per month if sufficiently enforced.

The sanctions have prompted Chinese and Indian refiners, which have bought heavily from Russia, to seek alternative supplies of crude oil. Many of the tankers hit by the latest measures have been used to ship oil to those two countries.

Peskov said modern experience had shown it was impossible to cut natural supply routes for energy.

"You block something in one place, and an alternative option appears somewhere else. Therefore, a search will be conducted for work options that will minimise the consequences of sanctions," he said.
